A variety of actuators is available for a wide range of application. by splitting moving contacts. The contact mechanism of models for micro loads is a crossbar Since the moving contacts are connected to a common terminal, type with gold-alloy contacts, which ensures highly reliable either parallel or series connection is possible. operations for micro loads. Highly reliable micro load switching is ensured if the model is used Contact Gap: as a twin-contact switch.

Maintained-contact Models

switch case, in addition to the pushbutton (plunger) located on the

Drip-proof opposite side of the reset button. Use these buttons alternately.
